How can I handle errors when using contextlib in Python?

You can use the contextlib module to manage resources and handle errors gracefully. Would you like an example?

Yes, please provide an example of using contextlib with error handling.

Sure! You can use contextlib.suppress to ignore specific exceptions. Here's a simple example:

from contextlib import suppress

with suppress(FileNotFoundError):
    with open('file.txt') as f:
        data = f.read()

This will suppress the FileNotFoundError if the file doesn't exist.

What if I want to log the error instead of suppressing it?

In that case, you can use a try-except block within your context manager to log the error. Here's an example:

import logging
from contextlib import contextmanager

@contextmanager
def open_file(filename):
    try:
        f = open(filename)
        yield f
    except Exception as e:
        logging.error(f'Error opening file: {e}')
    finally:
        f.close() if 'f' in locals() else None
